OBJECTIVE The purpose of this study was to determine the effect of two extraoral computer-aided design (CAD) and computer-aided manufacturing (CAM) systems, in comparison with conventional techniques, on the marginal fit of monolithic CAD/CAM lithium disilicate ceramic crowns. STUDY DESIGN This is an in vitro interventional study. PLACE AND DURATION OF STUDY The study was carried out at the...
The application of computer-aided design and manufacturing (CAD/CAM) techniques in the clinic is growing slowly but steadily. The ability to build patient-specific models based on medical imaging data offers major potential. In this work we report on the feasibility of employing laser scanning with CAD/CAM techniques to aid in breast reconstruction. A patient was imaged with laser scanning, an ...
مقدمه و هدف: در سالهای اخیر استفاده از زیرکونیا با معرفی تکنولوژی cad/cam در دندانپزشکی فزونی یافته است.مطالعات قبلی نشان داده اند علی رغم استحکام بالای زیرکونیا ، باند بین کور و پرسلن کم است که این نقص رستوریشن را مستعد پریدگی سرامیک پوشاننده می کند. استرس باقی مانده در محل اتصال سرامیک_ زیر کونیا بعلت عدم مطابقت ضریب انبساط حرارتی کلید شکست های رستوریشن پرسلن_زیرکونیا می باشد. تحقیق در مورد ن...
Aim: The aim of this study is to determine the cytotoxic effects Computer Aided Design (CAD) and Manufacturing (CAM) blocks produced by different companies on human peripheral blood lymphocytes MTT assay.
 Methods: Six CAD/CAM materials were investigated: feldspar ceramic VM (Vitablocks Mark II ), resin nano-ceramic LU (Lava Ultimate), hybrid C (Cerasmart), leucite-reinforced LRF (GC LRF),...
